Never ask that question again with the Freak. Instead, ask which insert you should use. Paint varies. So SmartParts invented a system that adapted to the paintball, not the other way around. One barrel, eight bore sizes. Buy a tiny ball: we have a .679 in

Never ask that question again with the Freak. Instead, ask which insert you should use. Paint varies. So SmartParts invented a system that adapted to the paintball, not the other way around. One barrel, eight bore sizes. Buy a tiny ball: we have a .679 insert. Medium ball: be happy with the .689. Buy big or just leave paint in the sun all day: we have .695. Freak inserts are subjected to the same rigorous honing and hardcoat anodizing as all Smart Parts barrels. They are held to strict tolerances to make sure your .684 is just that, not smaller or larger. That goes for Stainless Steel inserts, too. Stainless steel inserts are stronger and hone to a slightly smoother finish, giving you one more option in the Freak line. We’ve even started making an even larger bore insert, the .697, for the biggest paintball you can find. With eight insert sizes: .679, .682, .684, .687, .689, .691, .693, .695 you’ll always have the right insert for any paint.
